BATTERY-ZINC.

SPECIFICATION forming part of Letters l 'atent No. 593,332, dated November 9, 1897. Application filed December 24, 1896. Serial No. 616,835. (No model.)

To all whom it may concern.-

Be it known that I, DORA OGDEN, a citizen of the United States, residing at Columbus, in the county of Bartholomew and State of Indiana, have invented a new and useful Battery-Zinc, of which the following is a specification.

My'invention relates to an improvement in battery-zincs,more particularly the zines used in gravity-batteries.

The object of my invention is to produce a zinc which may be securely held in the battery solution until it is entirely dissolved, at the same time allowing the insertion of another similar zinc in order that the strength of the battery may be maintained.

The accompanying drawings illustrate my invention.

Figure 1 is a View in perspective of the most approved form of my improved zinc. Fig. 2 is a central vertical section thereof. Fig. 3 is a section showing means for suspending the zinc in the cell. Fig. 4 is a similar view showing the two zines mounted in the same cell, one'of said zincs having been partially dissolved by the action of the battery. Fig. 5 is a view in perspective of the supporting-saddle and attached parts. Fig. 6 is a vertical section thereof.

In the drawings, 7 indicates a zinc of any approved form, that shown in the drawings being the well-known spider pattern. Formed upon the upper face of zinc 7 is a lug 8. Passing down through lug 8 and through the body of the zinc is a connecting-rod 9, formed, preferably, of copper wire. Formed through the body of zinc 7 is an opening 10, through which the lug 8 of a similar zinc maybe passed, the arrangement of the opening and lug being preferably such that when one zinc is placed upon another with the lug of one engaging the opening of the other the two zines will be substantially concentric.

For the purpose of suspending the zincs in the cell I provide a saddle 11, which extends across the mouth of the cell and is provided with a pair of feet 12, adapted to engage the opposite upper edges of the cell. Mounted upon the saddle is a block 13, provided with a pair of holes 14 and 15, each adapted to receive the connecting-rodof one of the zincs. Set-screws 16 and 17 are provided to engage the rods passing through holes 14 and 15, re-

. spectively. Mounted upon block 13 is a suitable binding-post 18. For the purpose of centering the zines in the cell the block 13 is made adjustable on the saddle by means of the slot 19 and screw 20. In order to prevent the connecting-rods 9 from slipping through the block 13, the interior of holes 14 and 15 are preferably roughened, as by means of screw-threads, so that when the screws 16 and 17 are set down the projecting points will sink into the rods 9.

In operation the rod 9 of one of the zincs is secured in hole 14 of block 13, and the said block is adjusted along the saddle until the zinc is substantially centered in the cell. When the zinc becomes sufficiently dissolved, it is removed from the battery and from the saddle. A new zinc is then placed in position, the connecting-rod thereof passing up through the hole 15 and being secured therein by means of screw 17. Rod 9 and lug 8 of the old zinc are then passed through opening 10 of the new zinc and rod 9 refastened in hole 14. It will be readily understood, of course, that the new zinc may be placed below the old zinc without removing the old zinc; but it is the better practice to place the old zinc below. When the first zinc is entirely dissolved, a fresh zinc may be inserted therefor.

By the above-described means each zinc is independently held, and owing to the fact that rod 9 passes entirely through the zinc each zinc will be properly held in the solution until every portion thereof has been eaten up by the action of the battery.

It is to be understood that the termzinc herein used is intended to mean, broadly, an electrode, whether that electrode be made of zinc or of another material.

I claim as my invention- 1. The combination of an electrode, means carried thereby for interlocking with a similar electrode, and means by which two such electrodes may be independently held in a cell, the arrangement being such that one electrode will lie immediately beneath the other.

2. As an article of manufacture, an electrode having a lug formed on. one surface thereof, to one side of the center and a recess or opening formed in said electrode on the opposite side of the center, the arrangement being such that the lug of a similar electrode may be received in said recess, and

means for independently mounting each electrode in the cell.

3. As an article of manufacture, an electrode having a lug formed on one surface thereof on one side of the center, an opening formed through said electrode on the opposite side of the center, the arrangement being such that the lug of a similar electrode may be received in .said opening, and a connecting-rod, of material other than the material of the electrode passing down through said lug and through the electrode and being secured thereto, the arrangement being such that each electrode may be independently suspended by means of said rod.

4. As an article of manufacture, an electrode having a lug formed on one surface thereof on one side of the center, an opening formed through said electrode on the opposite side of the center, the arrangement being such that the lug of a similar electrode may be received in said opening, and a connecting-rod, secured to said lug, the arrangement being such that each electrode may be independently suspended by means of said rod.

5. The combination of a pair of electrodes each provided with means for engaging a similar electrode and each provided with a connecting-rod, a .saddleadapted-to extend across the mouth of a cell, an adjustable block carried by said saddle, means carried by said block for engaging the connecting-rod of each electrode, and a binding-post carried by said block, substantially .as described.

'6. The combination of a pair of electrodes each provided with means for engaging a similar electrode and each provided with a connecting-rod, a saddle adapted to extend across the mouth of a cell, and means carried by said saddle for engaging each of said connectingrods, substantially as and for the purpose set forth.

7. The combination with a pair of electrodes each provided with means for engaging a similar electrode and each provided with a connecting-rod, of means for engaging each of said rods and thereby independently suspending each electrode in the cell.

8. The combination with a pair of electrodes each provided with means for suspending it in the cell, one of said suspending means passing through the other electrode, of means for engaging said suspending means and thereby holding the electrodes independ-t A ently in the cell one above the other.
